Definitions

  • the present invention relates to a guide system for guiding at least one movably-supported door wing relative to a furniture carcass.
  • the guide system includes a first guide rail for guiding the at least one door wing, and a second guide rail for guiding the at least one door wing, in which the second guide rail extends transversely relative to the first guide rail in a mounted condition.
  • a carrier is configured to be displaceable along the second guide rail, and the carrier is connected or is configured to be connected to the at least one door wing via at least three furniture hinges arranged or to be arranged spaced from one another in the mounted condition, and the carrier has a longitudinal axis.
  • the invention relates to an item of furniture comprising a furniture carcass, at least one door wing movably supported relative to the furniture carcass, and a guide system of the type to be described for moving the at least one door wing relative to the furniture carcass.
  • the invention relates to a method for mounting a door wing to a carrier of a guide system of the type to be described.
  • a guide system for two door wings which are hingedly connected to one another and which can be inserted into a lateral insertion compartment of the furniture carcass via a carrier is shown, for example, in WO 2018/129574 A1.
  • US 2007/159037 A1 discloses a non-generic guide system for moving a door wing of a media cabinet.
  • the door wing covers the furniture carcass, so that a monitor arranged within the furniture carcass can be covered for example.
  • the door wing can be laterally inserted into the furniture carcass, so that an unhindered view onto the monitor can be made possible.
  • a displacement of the door wing along the front edge of the furniture carcass is not possible due to the lack of a guide rail.
  • FIG. 5 of the US 2007/159037 A1 reference it can further be seen that two furniture hinges for pivotally supporting the door wing are each arranged on two holding devices separate from one another.
  • the holding devices jointly with the furniture hinges and the door wing, can be inserted into the interior of the furniture carcass.
  • a drawback is the fact that the mounting procedure of the door wing is somewhat complicated, because each of the hinge cups of the furniture hinges must be precisely countersunk into corresponding openings of the door wing.
  • the adjustments of the furniture hinges must be coordinated to one another. Otherwise, this would lead to a misalignment, to a strain or to a jamming of the door wing.
  • US 2013/0232878 A1 discloses a guide system for a door wing which can be inserted into a lateral insertion compartment of a furniture carcass via a vertically extending carrier.
  • a plurality of hinges is provided, and the hinges can be arranged on a common profiled rail separate from the carrier.
  • the profiled rail For mounting the profiled rail, the profiled rail must be slid onto the carrier in a longitudinal direction.
  • a sufficient space must be present in a height direction. However, such a space is not available in most mounting situations.
  • all furniture hinges by which the at least one door wing can be connected or is connected to the carrier in the mounted condition, are arranged or can be arranged on a common mounting member separate from the carrier.
  • the mounting member is configured to be releasably connected to the carrier by at least one fastening device, and the mounting member is configured to be releasably connected to the carrier in a direction extending transversely to the longitudinal axis of the carrier.
  • the at least one door wing can be fixed to the mounting member via the furniture hinges.
  • the mounting member jointly with the door wing fixed thereon—can be slid onto the carrier in a direction extending transversely to the longitudinal axis of the carrier (for example from the front). Therefore, a comfortable and easily performed mounting operation of the door wing to the carrier can be afforded.
  • the mounting member can be releasably connected to the carrier by sliding onto, by pushing onto or by hanging the mounting member into the carrier.
  • All furniture hinges provided for fixing the at least one door wing are arranged or can be arranged on a common mounting member separate from the carrier.
  • the mounting member jointly the furniture hinges pre-mounted thereon, can be fixed as a common constructional unit to the carrier via at least one fastening device. Accordingly, it is not necessary to mount the furniture hinges individually to the carrier.
  • a special advantage of the invention lies in the fact that a position of the mounting member—jointly with the furniture hinges arranged thereon—can be adjusted relative to the carrier by at least one adjustment device.
  • all furniture hinges provided for fixing the door wing can be synchronically and uniformly adjusted relative to the carrier upon an adjustment of the mounting member. By a synchronous adjustment of the furniture hinges, strains or jammings of the door wing can be practically excluded.
  • the furniture hinges are either already pre-mounted to the common mounting member or, alternatively, can be configured to be releasably fixed to the mounting member.
  • recesses and/or locking elements may be arranged or formed on the mounting member, and the furniture hinges can be releasably locked (for example snapped) to the mounting member by the recesses and/or by the locking elements.
  • At least four furniture hinges are arranged or can be arranged on the mounting member.
  • the number of the furniture hinges certainly depends on the respective height and on the weight of the door wing. Therefore, more than four furniture hinges can also be provided on the mounting member, and the furniture hinges are spaced from one another in a longitudinal direction of the mounting member in a mounted condition.
  • the mounting member can be configured as a longitudinally extending rail.
  • the rail in a connected condition with the carrier, bears against the carrier substantially over its entire length.
  • the mounting member can have a one-piece configuration or also a multi-part configuration.
  • a multi-part configuration of the mounting member two or more partial portions can be provided, and the partial portions are configured to be fixed to one another (for example by a fastening adaptor and/or by screws).
  • the mounting member as a finished module, includes at least three furniture hinges for fixing the at least one door wing.
  • the at least one fastening device for fixing the mounting member to the carrier can include, for example, at least one protrusion arranged or formed on the carrier or on the mounting member.
  • the protrusion in a connected condition between the mounting member and the carrier, engages into a recess arranged on the mounting member or on the carrier.
  • the at least one protrusion can be formed or arranged either on the mounting member or on the carrier.
  • the protrusion engages into a corresponding recess of the carrier or of the mounting member.
  • at least two protrusions are provided, the protrusions being spaced from one another in a longitudinal direction of the mounting member and/or in a longitudinal direction of the carrier.
  • At least one adjustment device can be provided for adjusting a position of the mounting member relative to the carrier in a connected condition of the mounting member on the carrier.
  • the adjustment device can include at least one rotatably mounted adjustment wheel. By rotating the adjustment wheel, a position of the mounting member relative to the carrier can be adjusted.
  • the at least one adjustment wheel can include a tool receiving device, and the adjustment wheel can be rotated by rotating the tool receiving device with the aid of a tool, for example with a screwdriver.
  • a position of the mounting member relative to the carrier can be adjusted by at least one adjustment device.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a guide system for guiding at least one movably-supported door wing relative to a furniture carcass. The guide system includes a first guide rail for guiding the at least one door wing, and a second guide rail for guiding the at least one door wing, in which the second guide rail extends transversely relative to the first guide rail in a mounted condition. A carrier is configured to be displaceable along the second guide rail, and the carrier is connected or is configured to be connected to the at least one door wing via at least three furniture hinges arranged or to be arranged spaced from one another in the mounted condition, and the carrier has a longitudinal axis.
Moreover, the invention relates to an item of furniture comprising a furniture carcass, at least one door wing movably supported relative to the furniture carcass, and a guide system of the type to be described for moving the at least one door wing relative to the furniture carcass.
Moreover, the invention relates to a method for mounting a door wing to a carrier of a guide system of the type to be described.
A guide system for two door wings which are hingedly connected to one another and which can be inserted into a lateral insertion compartment of the furniture carcass via a carrier is shown, for example, in WO 2018/129574 A1.
US 2007/159037 A1 discloses a non-generic guide system for moving a door wing of a media cabinet. In a first position, the door wing covers the furniture carcass, so that a monitor arranged within the furniture carcass can be covered for example. In a further position, the door wing can be laterally inserted into the furniture carcass, so that an unhindered view onto the monitor can be made possible. A displacement of the door wing along the front edge of the furniture carcass is not possible due to the lack of a guide rail. In FIG. 5 of the US 2007/159037 A1 reference, it can further be seen that two furniture hinges for pivotally supporting the door wing are each arranged on two holding devices separate from one another. The holding devices, jointly with the furniture hinges and the door wing, can be inserted into the interior of the furniture carcass. A drawback is the fact that the mounting procedure of the door wing is somewhat complicated, because each of the hinge cups of the furniture hinges must be precisely countersunk into corresponding openings of the door wing. Moreover, when the furniture hinges are provided with an adjustment device, the adjustments of the furniture hinges must be coordinated to one another. Otherwise, this would lead to a misalignment, to a strain or to a jamming of the door wing.
US 2013/0232878 A1 discloses a guide system for a door wing which can be inserted into a lateral insertion compartment of a furniture carcass via a vertically extending carrier. For supporting the door wing, a plurality of hinges is provided, and the hinges can be arranged on a common profiled rail separate from the carrier. For mounting the profiled rail, the profiled rail must be slid onto the carrier in a longitudinal direction. In order for profiled rail to be slid onto the vertically extending carrier on-site, a sufficient space must be present in a height direction. However, such a space is not available in most mounting situations.
SUMMARY OF THE INVENTION
It is an object of the present invention to propose a guide system of the type mentioned in the introductory part, thereby avoiding the above-discussed drawbacks.
According to the invention, all furniture hinges, by which the at least one door wing can be connected or is connected to the carrier in the mounted condition, are arranged or can be arranged on a common mounting member separate from the carrier. The mounting member is configured to be releasably connected to the carrier by at least one fastening device, and the mounting member is configured to be releasably connected to the carrier in a direction extending transversely to the longitudinal axis of the carrier.
Accordingly, in a first mounting step, the at least one door wing can be fixed to the mounting member via the furniture hinges. In a further mounting step, the mounting member—jointly with the door wing fixed thereon—can be slid onto the carrier in a direction extending transversely to the longitudinal axis of the carrier (for example from the front). Therefore, a comfortable and easily performed mounting operation of the door wing to the carrier can be afforded.
According to an embodiment, the mounting member can be releasably connected to the carrier by sliding onto, by pushing onto or by hanging the mounting member into the carrier.
All furniture hinges provided for fixing the at least one door wing are arranged or can be arranged on a common mounting member separate from the carrier. As a result, the mounting member, jointly the furniture hinges pre-mounted thereon, can be fixed as a common constructional unit to the carrier via at least one fastening device. Accordingly, it is not necessary to mount the furniture hinges individually to the carrier. A special advantage of the invention lies in the fact that a position of the mounting member—jointly with the furniture hinges arranged thereon—can be adjusted relative to the carrier by at least one adjustment device. As a result, all furniture hinges provided for fixing the door wing can be synchronically and uniformly adjusted relative to the carrier upon an adjustment of the mounting member. By a synchronous adjustment of the furniture hinges, strains or jammings of the door wing can be practically excluded.
The furniture hinges are either already pre-mounted to the common mounting member or, alternatively, can be configured to be releasably fixed to the mounting member. For the purpose of releasably fixing the furniture hinges, recesses and/or locking elements may be arranged or formed on the mounting member, and the furniture hinges can be releasably locked (for example snapped) to the mounting member by the recesses and/or by the locking elements.
According to an embodiment, at least four furniture hinges are arranged or can be arranged on the mounting member. The number of the furniture hinges certainly depends on the respective height and on the weight of the door wing. Therefore, more than four furniture hinges can also be provided on the mounting member, and the furniture hinges are spaced from one another in a longitudinal direction of the mounting member in a mounted condition.
For example, the mounting member can be configured as a longitudinally extending rail. Preferably, the rail, in a connected condition with the carrier, bears against the carrier substantially over its entire length.
The mounting member can have a one-piece configuration or also a multi-part configuration. With a multi-part configuration of the mounting member, two or more partial portions can be provided, and the partial portions are configured to be fixed to one another (for example by a fastening adaptor and/or by screws). As a result, the mounting member, as a finished module, includes at least three furniture hinges for fixing the at least one door wing.
The at least one fastening device for fixing the mounting member to the carrier can include, for example, at least one protrusion arranged or formed on the carrier or on the mounting member. The protrusion, in a connected condition between the mounting member and the carrier, engages into a recess arranged on the mounting member or on the carrier. Accordingly, the at least one protrusion can be formed or arranged either on the mounting member or on the carrier. In a connected condition with the carrier, the protrusion engages into a corresponding recess of the carrier or of the mounting member. According to an embodiment, at least two protrusions are provided, the protrusions being spaced from one another in a longitudinal direction of the mounting member and/or in a longitudinal direction of the carrier.
As already mentioned before, at least one adjustment device can be provided for adjusting a position of the mounting member relative to the carrier in a connected condition of the mounting member on the carrier. For example, the adjustment device can include at least one rotatably mounted adjustment wheel. By rotating the adjustment wheel, a position of the mounting member relative to the carrier can be adjusted. The at least one adjustment wheel can include a tool receiving device, and the adjustment wheel can be rotated by rotating the tool receiving device with the aid of a tool, for example with a screwdriver.
The method according to the invention for mounting at least one door wing on a carrier of a guide system of the type in question is characterized by the following steps:
    • providing a mounting member separate from the carrier, and at least three or more furniture hinges for movably supporting the at least one door wing are arranged or can be arranged on the mounting member,
    • connecting the furniture hinges arranged on the mounting member with the at least one door wing, and
    • releasably connecting the mounting member to the carrier of the guide system.
According to a further method step, in a connected condition of the mounting member on the carrier, a position of the mounting member relative to the carrier can be adjusted by at least one adjustment device.

 DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 a shows a perspective view of an item of furniture 1 comprising a furniture carcass 2 and door wings 3 a, 3 b, 4 a, 4 b movably supported relative thereto. The door wings 3 a, 3 b, 4 a, 4 b can be moved by a guide system 5 between a first position, in which the door wings 3 a, 3 b, 4 a, 4 b are aligned substantially coplanar to one another, and a second position, in which the door wings 3 a, 3 b, 4 a, 4 b are aligned substantially parallel to one another. In the second (parallel) position, the door wings 3 a, 3 b can be inserted into a lateral receiving compartment 8 a of the furniture carcass 2. The other door wings 4 a, 4 b, in a parallel position to one another, can be inserted into a further receiving compartment 8 b. The functionality will be explained in the following with the aid of the door wings 3 a, 3 b, and the same descriptions apply to the other door wings 4 a, 4 b. The guide system 5 includes a first guide rail 7 a having a longitudinal axis (L), and a guide carriage 6 configured to be connected to the second door wing 3 b is displaceably supported along the first guide rail 7 a.
FIG. 1 b shows the item of furniture 1, in which the door wings 3 a, 3 b, from the coplanar position shown in FIG. 1 a , have been moved into an angled position to one another. The first door wing 3 a is supported on a carrier 11 via three or more furniture hinges 10. The carrier 11 is configured to be inserted into the receiving compartment 8 a in a depth direction (Z). The carrier 11, in the shown figure, is located in a transfer position in which the carrier 11 adjoins the first guide rail 7 a in the longitudinal axis (L) such that the guide carriage 6 can be transferred to and from between the first guide rail 7 a and the carrier 11. In the shown transfer position, the carrier 11 is releasably locked to the first guide rail 7 a, and the locking between the first guide rail 7 a and the carrier 11 can be released by an entry of the guide carriage 6 in or on the carrier 11. The carrier 11 is in the form of a longitudinally extending column, and a length of which corresponds to at least half of a height of the door wings 3 a, 3 b. The two door wings 3 a, 3 b are hingedly connected to one another about a vertically extending axis via a hinge fitting 9. The second door wing 3 b is displaceably supported along the first guide rail 7 a via the guide carriage 6.
FIG. 2 a shows the item of furniture 1 with the door wings 3 a and 3 b which are now aligned parallel to one another. The carrier 11 has been unlocked from the first guide rail 7 a by an entry of the guide carriage 6, so that the carrier 11 (jointly with the guide carriage 6 and the door wings 3 a, 3 b) can be inserted into the receiving compartment 8 a in the depth direction (Z) along a second guide rail 7 b (not shown) of the guide system 5, the second guide rail 7 b extending transversely to the longitudinal axis (L) of the first guide rail 7 a.
FIG. 2 b shows the item of furniture 1 with the door wings 3 a, 3 b which are now located in a fully inserted condition within the receiving compartment 8 a. The door wings 3 a, 3 b are thus movably supported by the guide system 5 from a first position according to FIG. 1 a , in which the door wings 3 a, 3 b are aligned substantially coplanar to one another, and a second position according to FIG. 2 b , in which the door wings 3 a, 3 b are aligned substantially parallel to one another and can be accommodated within the receiving compartment 8 a. In this way, for example, a kitchen 12 as shown in FIGS. 2 a, 2 b can be fully concealed, so that the kitchen 12 can be visually separated from a remaining area of a living room. In the shown embodiment, the receiving compartment 8 a is formed by a sidewall 13 a and by a stationary furniture part 13 b spaced in a parallel relationship from the sidewall 13 a. The two door wings 3 a, 3 b can be inserted between the sidewall 13 a and the stationary furniture part 13 b when the two door wings 3 a, 3 b are aligned in a parallel position to one another.
FIG. 3 shows a perspective view of the guide system 5 in a region between the sidewall 13 a and the stationary furniture part 13 b, between which the receiving compartment 8 a for receiving the door wings 3 a, 3 b is formed. The first guide rail 7 a has a longitudinal axis (L) extending parallel to a front edge of the furniture carcass 2 in a mounted condition. A second guide rail 7 b having a longitudinal axis (12) is arranged on the stationary furniture part 13 b, the longitudinal axis (L) of the first guide rail 7 a and the longitudinal axis (12) of the second guide rail 7 b extending transversely, preferably substantially at a right angle, to one another. The carrier 11 is configured for movably supporting the at least one door wing 3 a. The door wing 3 a, in a mounted condition, is pivotally supported about a vertically extending axis on the carrier 11 via at least three or more furniture hinges 10 (see FIG. 1 b ). The carrier 11 includes at least one guide device 14 for moving the carrier 11 along the second guide rail 7 b in the depth direction (Z) and in a direction opposite the depth direction (Z). In the shown figure, the guide device 14 of the carrier 11 includes at least one running wheel 14 a movably supported along a first running limb 17 a of the second guide rail 7 b.
In the shown embodiment, the carrier 11 is configured to be releasably locked to the first guide rail 7 a via a receiving device 15. The receiving device 15 is configured to receive the displaceable guide carriage 6, so that the guide carriage 6 can be moved from the first guide rail 7 a into the receiving device 15. For this purpose, guide grooves 20, 21 may be arranged in the first guide rail 7 a, the guide grooves 20, 21 extending along the longitudinal axis (L) of the first guide rail 7 a and being aligned, in the transfer position of the receiving device 15, flush with corresponding guide grooves 20 a, 21 a of the receiving device 15. In this way, the running wheels of the guide carriage 6 can be displaced between the first guide rail 7 a and the receiving device 15 without a disturbing abutting edge.
For the improved decoupling between the receiving device 15 and the carrier 11, it can be provided that the receiving device 15 includes at least one supporting roller 34 separate from the guide device 14 of the carrier 11, and the at least one supporting roller 34 is configured to run along the second guide rail 7 b. It can be preferably provided that the second guide rail 7 b includes a first running limb 17 a and at least one second running limb 17 b separate from the first running limb 17 a. The running wheel 14 a of the guide device 14 is movably supported along the first running limb 17 a of the second guide rail 7 b, and the at least one supporting roller 34 of the receiving device 15 is movably supported along the second running limb 17 b of the second guide rail 7 b.
The carrier 11 and the receiving device 15 are connected to one another in a movement-coupled manner upon a movement along the second guide rail 7 b in the depth direction (Z). It can be preferably provided that the receiving device 15 and the carrier 11, upon a movement along the second guide rail 7 b in the depth direction (Z) and in a direction opposite the depth direction (Z), are coupled to one another in a play-free manner. For the improved support of the carrier 11, at least one further guide rail 7 c can be provided, and a further running wheel 19 of the carrier 11 is displaceably supported along the further guide rail 7 c.
FIG. 4 shows a perspective view of the door wing 3 a, and a mounting member 16 for fixing to the carrier 11 is pre-mounted to the door wing 3 a. At least three (in the present case five) furniture hinges 10 are arranged on the mounting member 16 for pivotally supporting the door wing 3 a. In the shown figure, the mounting member 16 is configured as a rail extending along the longitudinal axis (L1) of the carrier 11, and the rail may have a one-piece configuration or also a multi-part configuration. The mounting member 16 is configured to be releasably connected to the carrier 11 in a direction extending transversely to the longitudinal axis (L1) of the carrier 11, preferably by hanging the mounting member 16 into to carrier 11.
The mounting member 16 includes at least one flat-shaped bearing surface 16 a bearing against a flat-shaped bearing surface 11 a of the carrier 11 in a connected condition with the carrier 11. By at least one adjustment device 35 a, 35 b separate from the furniture hinges 10, a position of the mounting member 16 relative to the carrier 11 can be adjusted in the connected condition. Preferably, a position of the mounting member 16 relative to the carrier 11 can be adjusted by the upper adjustment device 35 a in a lateral direction (X) and in a height direction (H), whereas a position of the mounting member 16 relative to the carrier 11 can be adjusted by the lower adjustment device 35 b only in a lateral direction (X).
The mounting member 16 is configured to be fixed to the carrier 11 via at least one fastening device 18 a, 18 b. In the shown embodiment, each of the fastening devices 18 a, 18 b includes a protrusion 19 a, 19 b (FIG. 5 ) arranged on the carrier 11. In a connected condition of the mounting member 16, the protrusions 19 a, 19 b engage in a corresponding recess 36 a, 36 b of the mounting member 16.
